Decentralization currently particularly strong in most cases. The CurveBS core consists of three parts: ### 1. Metadata Server (MDS) - Manages and stores metadata information and persists the data in ETCD ☑ Collect cluster status and schedule read and write data interfaces for upper-layer applications ● Interacts with MDS to add, delete, modify, and query metadata ● Interacts with the chunkServer to read and write data ### 4.

como servidor remoto, para permitir que os clientes conectem ao banco através da internet. Terminal server (Windows ou Linux/Unix) é uma alternativa interessante para implementar esta estrutura. Desta forma prever tal atividade. Você pode vir a considerar a construção de sua própria versão do Firebird server, com a senha de desencriptação escondida no executável. Mas descompiladores são facilmente encontrados
